CONFECTIONERY-MACHIN E.

SPECIFICATION forming part of Letters Patent No. 533,397, dated January29, 1895.

Application filed March 31, 1894.

To all whom it may concern.-

Be it known that I, JOSEPH H. SMITH, acitizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inConfectionery-Machines, of which the following is a specification.

This invention relates to certain new and useful improvements inmachines for dropping confectionery and cake-dough.

The machine is of the same class as that for which Letters Patent of theUnited States were granted me July 22, 1890, No. 432,912, and the objectof the present invention is to provide such improvements as willincrease the capabilities of that machine, make it more efficient andadapted for a wider range of work, and more convenient in use.

The invention is illustrated in the accom panying drawings, in which-Figure 1 is a top or plan view of the machine. Fig. 2 is a sideelevation of same. Figs. 3 and 4 show the mechanism for adjusting themovement of the slide cut-0d in order to determine the size of the doughcutofi openings. Fig. 4 shows a partial register of the dough-openings.Fig. 5 is a vertical section of the elevator parts. Fig. 6 is anelevation of the elevator,-being a vertical cross-section of themachine. Figs. 7, 8 and 9 are details of the clutch mechanism. Figs. 10and 11 are views of the adjustable cam which varies or regulates thetime during which the dough cut-off openings are open. Fig. 12 is aninverted or bottom View of the receiver showing the drop-tubes andwire-carrying frame. Fig. 13 is a cross-section of same on the linel313.

In the drawings herewith all parts which are shown in my former patentare here designated by letters of reference the same as those employedin said patent, and all parts comprised in the improvements now about tobe described are designated by numbers.

The frame, A, may be of any preferred construction. A receiver, B, forthe confectionery or cake-dough is mounted on the frame, and has abottom, D, provided with openings or tubes, E, and an inner slidecut-off, F, rest- Serial No. 505,809. (No model.)

ing on the bottom. A follower, H, is in the receiver and two screws, I,rigidly'attached thereto press it down and raise it. A crane arm, 1,extends entirely across the top of the receiver and at each side has ashort lateral arm. In plan view the crane-arm has the form of a cross.See Fig. 1. Each follower screw, 1, passes vertically through aninternally-screw-threaded sprocket-wheel, 7, which is mounted on one ofthe lateral arms so as to revolve thereon. The revolution of thesescrew-wheels, 7, causes the screws, I, to raise or lower. At one side ofthe receiver is a vertical standard, 2, mounted in bearings, 3, so as toturn, and the crane-arm, 1, is attached 'to the upper end of saidstandard, 2. By this construction, when the follower, H, is raisedentirely out of the receiver, the follower and the bolts are in theslots, serve to tighten on the head of the crane-arm, and thereby firmlyhold said arm against the lifting strain of the So screws, I, at thetime the follower, H, is be- "ing pressed down.

The top-end of the standard, 2, has a double sprocket-wheel, 8i. e., awheel with two faces or two sets of sprockets. An endless chain, 9,passes about the two internally-threaded sprocket-wheels, 7, and aboutthe lower face the sprocket-wheel, 8. Another endless chain, 10, passesabout the upper face of thesprocketwheel, 8, and about a sprocket-wheel,11, on 0 the upper end of a revoluble shaft, 12. By this arrangementwhen the shaft, 12, is revolved both of the threaded sprocket wheels, 7,turn and thereby act on the screws, I. When the shaft revolves in onedirection it causes 9 5 the follower, H, to press down on the dough inthe receiver, and in the opposite direction it causes the follower to beraised.

The vertical shaft, 12, turns in bearings, 13, 13, and on its lower endhas a bevel wheel, 14, too

which gears with another wheel, 15, loose on a horizontal shaft, 16,extending in a direction crosswise of the machine. This shaft has apinion which gears with a cam wheel, 17, by which it is turnedcontinuously. Clutch mechanism is on the horizontal shaft, 16, and isemployed to transmit the motion of that shaft to the vertical shaft, 12at the moment it is desired to cause the screws, 1, to press down thefollower, H. This clutch is constructed as follows: The bevel wheel, 15,is always in gear with the wheel, 14, but, as already stated, is looseon the shaft,16, and its hub has teeth, 18. A clutch hub, 19, is on theshaft, 16, and by means of an ordinary spline and groove is movablelongitudinally thereon but must revolve with the shaft. This clutch hub,19, has teeth to engage with the teeth, 18, on the wheel, 15, and alsohas an exterior circumferential groove, 20. Abell-crank lever, 21, has abifurcated or forked end, 22, which partly encircles the clutch hub andisprovided with lugs which engage the circumferential groove, 20. Themovement of the bell-crank lever causes the clutch hub to slide on theshaft, 16, and engage or disengage the wheel, 15.

The letter, V, designates the driving-shaft and V, the pulley on it bywhich motion is imparted to it. The shaft, S, carries the camwheel, 17,and also a crank-arm, Z, to which one end of the operating rod, A, isattached while the other end is attached to a lever, B, pivoted looselyon the end of a shaft, 0, mounted at one end of the frame. This shaftcarries a ratchet-wheel, F. The lever, B, carries a pivoted pawl or dog,D, which engages with the ratchet-wheel, F. A curved plate, 23, issecured o the side of the frame so as to have position above the pawl ordog, D. This curved plate has such relation that the upper end of thepawl or dog will strike it and be released from the ratchet-wheel, Fwhen the lever, B, is near the end of its forward throw. Then on thebackward throw of the lever the pawl or dog moves away from the curvedplate. By the arrangement here described the continuous rotation of theshaft, S, causes an intermittent rotary motion of the shaft 0, same asin my former patent.

The intermittently-revoluble shaft, 0, has two large chain wheels, H,and a shaft mounted at the opposite end of the frame carries two smallchain-wheels, K, while endless chains, 1, pass around and connect thelarge wheels, H, and the small wheels, K.

' Two parallel longitudinal rails serve for the upper stretch of thechains, 1, to slide along, and the trays which are to receive the dropsof dough are to be placed upon these chains at one end of the machineand thereby are carried to the other endpausing at intervals by reasonof the intermittent movement of the chains. The slide cut-off, F, is athin plate having openings corresponding in number, size and location tothe openings or tubes, E, in the bottom, D, of the receiver. This plate,F, lies flat on the said bottom, D, and slides in and out at one sidethrough a narrow slot in the lower part of the wall of the receiver. Alink or links, N, connect this cut-01f plate, F, with pendent arms, 24,fixed on a rock-shaft, 25, extending crosswise and mounted in bearings,26.

The slide cut-off plate has a reciprocating movement in and out.

The material cake-dough, gu m-work, creamwork, or whatever may be in thereceiver is forced through the openings in the slide outoff plate, F,and the openings or tubes, E, in the bottom when the said openings ofthe slide-plate are coincident with the openings or tubes, E. When theplate, F, slides one way these two sets of openings are coincident, andwhen it slides the opposite way the holes are not coincident and in thismovement the slide-plate acts as a cut-off to cut the material and allowthe small particles cut off to drop onto the trays.

It is important to be able to adjust or regu late the movement of theslide-plate, F, in order to determine the size of the dough-cutoffopenings, that is, where it'is desired that the two sets of openingsshall register with each other to an extent less than the full size ofthe opening, as shown in Fig. 4. In order to efiect this regulation thefollowing mechanism is employed: A lever, 27, has its upper end loose onthe rock-shaft, 25, and its lower end carries a roller, 28, which takesin the cam'groove, 29, on the wheel, 17. By means of the rotation ofthis wheel the cam-groove has the effect to vibrate the said lever, 27.The rock-shaft, 25, has a pendent-plate, 30, provided with a hub bywhich it is rigidly attached alongside of the lever, 27, which is loose.This pendent plate has on its side two lugs, 31, each of which has anadjusting screw, 32, the ends of which point toward each other. Thesetwo screws, 32, take on opposite sides of the lever, 27, as shown inFigs. 2, 3 and 4. By means of the adjusting screws, 32, the relativeposition on the rock-shaft, 25, of the lever, 27, and the pendent arms,24, may be varied or changed enough to have the doughopenings in theslide-plate, F, register only partially with the openings or tubes, E,in the bottom, D, as seen in Fig. 4*. It is also important to be able toregulate and vary the time during which the two sets of dough cutoffopenings are in register with each other. In order to accomplish thisregulation I have provided an adjustable cam to coact with the lever,27. This cam is shown in detail in Figs. 10 and 11.

The wheel, 17, is mounted on the shaft, S, rigidly and has a hollow faceformed by the peripheral flange or internal rim, 33, which has anin-curve, 34. The wheel also has a hub, 35. A movable cam, 36, setswithin the hollow face of the wheel and has a sleeve, 37, which fitsloose around the hub, 35, so as to turn thereon. The sleeve carries aworm, 38,

'in bearings, 39, fixed to the sleeve, and the IIO ' screws.

worm has a crank, 40, to turn it. A collar, 41, surrounds the hub, 35,on which it is fixed tight. This collar has a segment-shaped rack, 42,which meshes with the worm, 38.

By turning the worm-crank, 40, the cam, 36, may be shifted or rotatedabout the hub, 35, so as to adjust its curved face (which, with the rim,33, forms the cam-groove, 29) relative to the fixed in-curve, 34, on thewheel. By this means the dough cut-off openings may be kept open alonger or shorter time.

I provide mechanism to elevate a tray above the chain carriers, 1. Thiselevator lifts only that tray which pauses immediately below thereceiver. The elevator mechanism is shown in detail in Figs. 5 and 6. Ahori zontal plate, 43, serves to lift the tray referred to. This platerises and falls between the two endless chains, I, and is mounted on twovertically-movable standards, 44, which are in guides, 45. The lower endof each standard has a lateral foot, 46. A rock-shaft, 47, extendsacross the frame and carries .two lever arms, 48, and a connecting rod,49, connects the lateral foot, 46, of each standard with the end of eachlever, 48. These connecting rods, 49, are extensible by means of Therock-shaft, 47, also carries two shorter lever arms, 50, projecting inthe opposite direction from the other lever arms, and each of theseshorter arms has a roller, 51, and a cam, 52, acts on the said roller.The two cams, 52, are mounted on the same revoluble shaft, S.

It will be seen that the revolution of the shaft, S, and the cams, 52,has the effect to lift the elevator plate, 43, up to the openings ortubes, E, in the bottom of the receiver.

A feature of the invention is the combinations whereby the follower, H,in the receiver has pressure brought on it intermittently the pressurebeing exerted by the revolution of the screw-threaded wheels, 7, at theinstant ofa pause in the movement of the chain-carriers.

A feature of the invention is the combinations whereby the follower, H,has pressure brought on it intermittently-the pressure beingexerted atthe instant the elevator is up; also in this connection the movement ofthe slide cut-off plate, F, to allow the dough to drop from thereceiver.

A feature of the invention is the combinanations whereby the follower,H, presses the dough at the instant the slide cut-01f plate, F, moves toopen the drop-tubes, E.

While there are other features of invention, these are here mentionedonly by way of pointing out the mode of operation of these parts.

The foregoing parts have reference to operating with material, to beplaced in the receiver, that is thin, in distinction to stiff. Where thematerial operated with is stiff or tight dough, as it is termed, Iprovide a wire cut-0E device to clip the dough from the drop tubes, E.This device is shown in Figs. 12, 13, 2 and 5.

A rectangular frame, 53, see Fig. 12, has,'in the present instance, fourwires, 54, stretched across it. The two opposite sides to which thewires are attached fit loosely in horizontal slides, 55, in which theframe reciprocates. The two slides, 55, which are at opposite sides ofthe frame, A, are vertically movable. Each slide,'55, is mounted at theupper end of a vertical rod, 56, which moves up and down in two guides,57. The lower end of the rod has a roller, 58, which rests on a cam, 59,on the end of a cross-shaft, 60. This cross-shaft has a sprocket-wheel,61, and is driven by a chain, indicated by the line 62, passing over asprocket-wheel,'63, on the shaft, S. The action of the cams, 59, on therollers and rods, 56, is to elevate and lower the frame, 53, whichcarries the wires. This frame is caused to reciprocate by two links,64,-one attached at each end-and each link connected with an uprightpivoted arm, 65, and a horizontal rod, 66, connecting each arm to thelever, 27, so that as this lever vibrates this mechanism will cause theframe, 53, to reciprocate in the slides, 55.

The wire cut off device may be dispensed with in some cases when theslide cutoff plate, F, is used, and in other cases both may be usedtogether. The slide cut-off plate, F, may be dispensed with in somecases when the wire cut-off is used.

The clutch mechanism for setting in motion the screw-threaded wheels, 7,to cause the follower, H, to press downward, is actuated by the movementof the horizontal rod,

66, which is connected with the lever, 27. This rod, 66, has a pendentfinger, 67, (see Figs. 7.and 8, also Figs. 1 and 2) which, when the rodmoves, comes in contact with the bellcrank lever, 21, having thebifuracted end, and by moving this lever causes the clutch hub, 19, toslide and engage with the teeth, 18, on the bevel wheel, 15, and therebysetin motion the vertical shaft, 12, chain 1O,sprocketwheel, 8, chain,9, and the two screw-threaded wheels, 7, which act on the followerscrews, I.

From the foregoing description the operation or action of the partswillbe understood. I may state, however, that all the parts of themachine are connected up so as to work antomatically.

When it is desired to replenish the receiver, B, the motion of themachine is first stopped. Then the follower, H, is raised by turning thehand-crank, 68, on the bevel-wheel, 15. When the follower is above thetop edge of the receiver the cam-levers, 6, are turned to release thetwo bolts, 5, from the slots, 4. Then the crane-arm, 1, screws, I, andfollower, H, may be swung laterally on the pivoted standard, 2, and thusuncover the top of the receiver.
